Marling describes one of the responses to The OA that moved her the most, a video that a young man sent her. “Can I set it up for a second?” Batmanglij asked. “He’s visiting his grandma for the weekend, and he goes and he finds her to say goodbye.” Marling picked up the story. “She’s standing in the backyard, she’s 80 years old, and she’s standing in the sun, the late sun coming at the end of the day, and she’s doing this. [She mimics the movements from the show.] And he’s like, ‘Grandma, grandma, what are you doing?’ And she’s like, ‘I’m going somewhere.’” Marling smiles. Things like that can daze you, she said. When you think about it, it’s miraculous. “You can touch strangers, and they can touch you back.”
